Due hardware problems, I could not join this discussion earlier, but I can confirm all conclusions: uLister works on Windows XP and require Visual C++ 2013.
Also note that version 3.0 of uLister can acts as a packer plugin which allows to mass convert files with packer interface.

It is mostly just enough to have the DLL in search path (but that is depending on the program who needs that DLL and how it is build)
So just install VC++2013 onec and copy the DLLs. Report back if that works for you.

I have 64-bit computer with the latest Windows 10 version, 64-bit TC installed and 64-bit Ulister plugin in it with the latest (8.5.4.) 64-bit Oracle "rdist" directory inside (downloaded from Oracle website, as per instructions in the Ulister Readme file).

At some point every time I pressed Ctrl+Q or F3 (and subsequentially the Ulister plugin was called by the TC, and the Ulister passed the command to "rdist" dll files), the whole TC just crashed and closed.

What I did to solve this problem is to start using 32-bit TC with 32-bit Ulister plugin and 32-bit Oracle "rdist" directory.
So now everything works properly.

However, it means that at the moment 64-bit Ulister passes its command to 64-bit Oracle dll files, something gets wrong...

There is no such general problem with the x64 ULister plugin and its Oracle files.
I use them daily with no crashes or other problems.
What type of files do you try viewing ?

64-bit Oracle "rdist" directory inside (downloaded from Oracle website, as per instructions in the Ulister Readme file).

How did you get "rdist" name? Did you read my previous message?
There are 32- and 64-bit libs, so they should be copied to redist32 and redist64 subdirs respectively.

Did you read other messages with advice to install proper VC redist packages?
There may be problems because you seem to have messed something…
